AUTOMATIC SAFETTI BUMPER.

Application led January 11, 1924.] Serial No. 685,556.

To all whom t mag/,Concerm' Be it known that we, PERRY JASPER JEssir and STErHnN ADRIAN NooNnR, citizens of the United States, residing at Atchison, in the county of Atchison and State of Kansas, have invented certain new and useful Improvements in Automatic Safety Bumpers, of which the following is a specification.

The present invention relates to an automatic safety bumper for use upon rails to engage the trucks of a car or cars compris ing a plurality of sections adapted to rigidly engage the rail.

A further object of the present invention is to provide a bumper arcuated to conform to the curvature of a car wheel and means for securing the sections rigidly together without bolting through the rail.

A still further conception of the invention will be had as the detailed description proceeds and referring more in detail -to the drawing7 wherein like reference characters indicate like or corresponding parts throughout the several views,

Figure 1 is a side elevation of the present invention,

Figure 2 is an end elevation showing the arc construction,

Figure 3 is an end elevation ylooking at the opposite side,

Figure 4 is an enlarged detailed side elevation of the intermediate section C, and

Figure 5 is a plan view looking down on the bumper.

Referring more in detail to the drawing,l

the bumper comprises side plates A and B and an intermediate plate C. The side plates A and B are provided with downwardly extending portions 1 at the base of the same adapted to fit tightly against the web of the rail X and engage the contour of the intermediate plate C. The side plates A and B are embraced through the short ribs 2 and are cut at an angle as shown at 3 so as not to interfere with the spikes which hold the rail to the tie rod. The side plates A and B are provided with an offset portion 4 cut back to the approximate width of the rail X. i

Spaces 5 are provided betweenside plate A and intermediate plate C and side plate B and plate C to allow for the reaction of the bumper when engaged suddenly with the wheel of a car truck, while a space 6 is provided between the intermediate plate Q and the ,rail X to allow for e gripping action upon the rail when operated. The intermediate plate C is arcuated as at 7 .to

approximately the radius of a standardcar wheel. This arc is constructed the width of the rail and cast or otherwise formed onto the edge of the plate C isa flange 8 cooperating with the arcuated portion `7 At l therbottom of the intermediate plate C there are providedrnotches or biting teethA 9 adaptfl ed to engage the rail X when pressure yis brought upon the plate C. For the purpose .Of resiliency the plate C is providedfwith cut out portions 10 and 11. l

Holes 13 are formed in the .side plates A and B and slotted or velongated holes 14 are formed in the intermediate plate C inl parallel alinement with the holes 13 in plates. A and B. By this construction the side plates A and B and intermediate plate C can be clamped over the rail without bolt-V ing through they rail and allow the plate C to grip the rail X when pressure is applied by the car wheel. Bolts 15 rigidly secure the side plates A and B and plate C in assembled relation. l i

The base 12 of the plate C is lnotI as wide as the rail ball. This is done in order that the plates A, B and C lit tightly over the rail and as soon as pressure is applied on the plate C, and the arc 7 and flange 8, it will draw the weight on the notches or teeth 9. When the weight is applied on the notches 9it will have atendency to raise the bottom l over the plates A and B against the bottom of the rail which will make a complete automatic grip and not permit the bumper to slide on the rail.

rl`he inner face of plates and B and bottom sides of C are practically smooth so .p

and flat and in practice the plates 'A B and C are clamped over the rail with another set of plates of the same construction directly opposite on the other rail, making a complete automatic bumper on each rail for the trucks of the car or cars. The bumpers when installed as described provide a most Our automatic rail plyalx'nps may be manu- Y lectured at and prodiiced at a 10W cost and f as Will be evident, may be readily7 and con- Veniently installed at very little expense.
